NUMERICAL STUDIES OF FLOWS IN A PERIPHERAL-JET-TYPE AIR-CUSHION

The flow in a peripheral-jet-type air-cushion is calculated numerically on the basis of the exact equations of fluid mechanics (Navier-Stokes equations). As the results, the distributions of streamlines, equivorticity lines and pressure are obtained, which indicate that numerical calculations of the exact equations are applicable to the flow of such complex configurations as air-cushions.
